42. RAD – Through Object Oriented Programming Rapid Application Development

43. Object Oriented Programming Objects and Classes • Object – A piece of data which represents a real world object, or sometimes an imaginary object.

44. Object Oriented Programming Objects and Classes • Object – A piece of data which represents a real world object, or sometimes an imaginary object. • Class – A data-type which describes an object to the compiler. A classification of objects.

45. Object Oriented Programming Objects and Classes Consider a class named ‘TCar’ (Delphi developers often use the letter ‘T’ to prefix a class name)

46. Object Oriented Programming Objects and Classes Consider a class named ‘TCar’ (Delphi developers often use the letter ‘T’ to prefix a class name) The TCar class desribes an object which has a number of wheels, and a number of doors.

47. Object Oriented Programming Objects and Classes Consider a class named ‘TCar’ (Delphi developers often use the letter ‘T’ to prefix a class name) The TCar class desribes an object which has a number of wheels, and a number of doors. The Object (an instance of the TCar class) is a piece of RAM reserved to represent the car, suppose it contains this data… Kind: SUV Wheels: 4 Doors: 5 Kind, Wheels and Doors are all referred to as Properties.

48. Object Oriented Programming Objects and Classes Using the TCar class, a software engineer is able to create multiple instances of this type of data in memory. For example. Kind: SUV Kind: Sport Wheels: 4 Wheels: 4 Doors: 5 Doors: 2

49. Object Oriented Programming Objects and Classes Classes are hierarchical. Our TCar class could be ‘descended’ from an ‘ancestor’ class of TVehicle. TVehicleTCar TMotorcycle TBicycle TTrain TPlane All of the descendant classes remain a class of vehicle even it they represent a more specific type of vehicle. This is called ‘Sub-Classing’.

50. Object Oriented Programming Objects and Classes TPlane, for example, could be further sub-classed into TBiplane, and TJet TVehicle could be a sub class of Ttransportation… Ttransportation TVehicle TPlane TCar TTeleporter
